Resumen
The third problem focuses on the study of robust and reconfigurable disassembly cell formation problems. This part of the research makes a significant contribution to the state of the art in Disassembly Systems Design and Cellular Manufacturing Systems for two reasons: first we consider two different approaches to deal with demand variability in disassembly systems: one reconfigurable and the other robust. In the reconfigurable approach the product demand varies form period to period in a deterministic manner; while in the robust approach the product demand varies in a random manner, however, this variation can be described in a number of probabilistic scenarios with a given occurrence probability. The problems are characterized and formulated as integer programming models. Second, given the complexity of the problems, we design a Variable Neighborhood Search (VNS) algorithm to efficiently solve them. The experimental analysis on a set of adapted (previously published) and randomly generated instances shows the good performance of the proposed algorithm.
